JAMES BRIGGS, OF IDLE, NEAR BRADFORD, ENGLAND.

SCAVENGERING-MACHINE.

SPECIFICATION forming part of Letters raient No. 719,733, dated February3, 1903.

Application filed February 6, 1902. Serial No. 92,915. (No model.)

rotary brush at the rear end of the vehicle;-V but the brush in thiscase is parallel to the axis of the vehicle. Immediately in front of thebrush is an inclined plate, the rear edge of which touches or almosttouches the ground, and a series of troughs, buckets, or carriersmounted upon endless chains pass up from beneath the front of theinclined plate and collect the material thrown over the plate by thebrush. The endless chains move in the direction required to carry thebuckets upward and then pass over pulleys or guide-wheels at the top,where the buckets are inverted to discharge their contents into a largereceptacle beneath. The buckets and chains are preferably inclosedwithin a suitable casing to prevent the material being blown about, andthe buckets or carriers are of such a form that there is no spacebetween them while they are getting filled whereby the material canescape.

To fully describe my invention, reference is made to the accompanyingsheets of drawings, forming a part of this specication, in which similarreference-numerals indicate corresponding parts in each of the views.

Figure 1 is a side elevation of my improved machine with certain partsnot material to the explanation of the invention omitted. Fig. 2 is aplan View of the same with the middle of the brush broken away. Fig. 3is a back View of the same. Fig. 4 is an end View, on a larger scale, ofone of the buckets attached to the link of one of the endless chains;and Fig. 5 is an elevation of the same, a portion of the bucket beingbroken away.

The body 2 of the vehicle is mounted on Vfour wheels, only shown inoutline by the broken lines 3, the front pair of which are mounted on aswiveling under-carriage in a similar way to an ordinary four-wheeledroadvehicle.l A sprocket-wheel 5 is fixed on the nave 6 of the near backwheel, and an endless pitch-chain 7 ,workin g thereon, drives thesprocket-wheel 8 on the stud 9 and rigidly connected to the spur-wheel12, engaging the pinion 13 on the end of the shaft 14 of the brush 15.The spindle 14 is mounted in bearings in the ends of the arms 16 and 17,rigidly connected to a shaft 18, journaled in bearings mounted onbrackets 20, projecting from the back of the vehicle. An arm 24 is fixedto one end of the shaft 18 and is adjusted by the screw 25 andconnecting-rod 26 to regulate the pressure of the brush l5 upon theroad. The short chain 28 is introduced between the end of the rod 26 andthe arm 24 to-allow the brush to lift when passing irregularities in theroad. When the vehicle is drawn along in the direction of the arrow,Fig. 1, the brush is rotated in the opposite direction to the wheel 5and throws all loose material it engages up the inclined plates 30immediately in front into the traveling buckets 31, carried by theendless chains 33. The buckets 31, moving in the direction of the twoarrows, Fig. 1, carry the material up and passing over the guide-wheels36 and 37 are inverted, and consequently drop their contents into thereceptacle 38, which is made with an inclined bottom 39, so that whenthe side door 40 is loosened the contents of the receptacle will slideont.

The shaft 50, carrying the sprocket-wheels 37, is driven by the chain 61from the sprocketwheel 52 on the nave of the off back wheel.

The plates 30 are attached to the cross-bar 34, supported by thebrackets 20 in such a way that they are free to be lifted to allow themto pass over obstacles in the path.

I claim- In a device of the class described, the combination with thevehicle-body, of brackets projecting therefrom, a rock-shaft journaledin said brackets, arms on said rock-shaft, a brush journaled in saidarms with means for rotating it, an endless carrier cooperating with IOOsaid brush, an upright arm on said rock-shaft, In Witness whereof I havehereunto set my a rod sldingly supported beneeth the body hand inpresence of two Witnesses. of the vehlole, a, cham conneotlng sald rodJAMES BRIGGS With said upright arm, a threaded rod at the 5 front of thehand-Wheel engaging a threaded Witnesses:

portion on said rod, and a hand-Wheel on said DAVID NOWELL, threadedrod, substantially as described. SAMUEL DRACUP.
